The first Injustice game had an interesting concept and turned out pretty good. The sequel expanded on the ideas and gameplay from the first and made drastic improvements. I don't personally like how much DC uses the Injustice storyline but I think the games work well. I especially like all the different DLC characters. The RNG system and outfits are awful but the game still has its pros.
Literally just feels like Mortal Kombat but with DC characters. Kind of enjoyable but it gets old rather fast because you're using the same fatality over and over. You are also dependent on the stats on your gear which makes this game almost a little pay to win since you can get matched against someone with completly different stats and much much better gear than your gear (which is a pain in the ass if you're a new guy). Otherwise great set of characters and guest characters, enjoyable story and the same type of combat as Mortal Kombat. So if you like DC and Mortal Kombat please give this game a shot.
